Mr. Speaker, the Leader of the Opposition, because he is a privy councillor, has been offered a full and complete briefing on all matters with respect to this situation, both classified and unclassified, so he can be fully informed. If he willfully refuses to be fully informed, it appears that his only objective is a political game that has nothing to do with the truth.
In the House of Commons on March 29th, 2018. See this statement in context.
